• Scott Disick is still having a difficult time two months after Kourtney Kardashian's engagement to Travis Barker
  • Disick is reportedly looking for support that is why he has been seeing Kourtney's younger sister, Kim Kardashian
  • Kim has been a "good ear" for Disick because the SKIMS founder understands him

Scott Disick is still not over Kourtney Kardashian's engagement to Travis Barker.

Disick, 38, and Kourtney, 42, had an on-again, off-again relationship for almost 10 years. He was allegedly hoping they would still reconcile after they split in 2015. So, when Kourtney said "yes" to Barker's proposal in October, he was very hurt and is "still so upset" about the engagement until today.

"He's been doing the best he can, but it's been a very difficult time for him," an unnamed source told People. "He's looking for support right now."

The couple share three children: Mason, 12, Penelope, 9, and Reign, 7.

The tipster added that Disick's feelings toward her engagement were "a big reason" why he had been spending some time with Kourtney's younger sister, Kim Kardashian. The SKIMS founder has been a "good ear" for him because she understands him.

Kourtney's siblings have been supportive of Disick for her even after their split six years ago. In one episode of "Keeping Up With the Kardashian" Season 20 in April, Kourtney Kardashian, Kendall Jenner and Kim made it known that they were still rooting for the exes to get back together.

They speculated that Kourtney and Disick were only waiting for who would make the first move. So, they set up a dinner date for the two of them. But Kourtney and Disick used the romantic scene to prank the family back.

"Dinner was very nice, but we're not back together. Maybe we're just getting back at you guys for meddling," Kourtney said.

"I'm rooting for them," Kim said.

"I think we're all rooting for them," Khloe added, sharing Kim's sentiment.

"I am Team 'Scourt,'" Kendall said before adding that Kourtney would "literally kill me for saying anything." The model noted that she understood their relationship, and she could tell how much they truly loved each other.

When Barker proposed to Kourtney, her family was also supportive of them. Following their engagement, Disick distanced himself from the Kardashian-Jenner family to "make his peace" with the engagement news.

Disick was hoping the couple would split and when they got engaged, he felt "being forced to deal with it, which is uncomfortable." Disick has been out on the dating scene after his split from Amelia Hamlin. He was recently linked to Hana Cross. However, he was reportedly not serious about her.

"He's having fun with Hana, but that's all it is for now," a source told E! News last month.
